which the following is a specification.

"My invention rel'atesto improvements .-in beetcutters inwhi'chtheknivesand knife blocks are held in a stationary positionand the beetsare rotated during the cutting or i slicing operation.

The objects of this arrangement are primarily to increase capacity overexisting machines, to facilitate. inspection,-removal or renewal ofknives and knife blockswhile the cutter is inoperation. Another objectis betterslices or cossettes,as they are/known in" the beet sugarmanufacturing industry, as centrifugal force does not break the.cossettes at high rotational speeds in my cutter. Centrifu al forceinstead aids in cansingthelieets to track and therefore produce uniformcossettes. I I

Iattain these objects by the mechanism illustrated in the accompanyingdrawings.

Figure 1 is ahalfsectional plan of assenr bled'cutter taken at CDofFigure 2 and halffull plan. Figure 2'is a sectional elevation ofassembled cutter taken at AB of Figure 1. Figure 3 is a sectional planof a knife block and one guide taken at E--F of Figure 1. Figure 41 isan elevation of a knife block and one guide viewed from the inside orcutting side. Figure 5 is a sectional elevation of a knife block takenat GH of Figure 3. Figure 6 is a part plan of a blank knife block.Figure 7 is a sectional elevation of the guide and frame taken at JK inFigure 3. Figure 8 is a sectional elevation of a feeding device taken atLM in Fig. 9. Figure 9 is an elevation of a feeding device.

Similar numerals refer to similar parts thruout the several views.

The casting land the semi-rings 1 and 1*, Figures 1 and 2 constitute themain frame which are in turn supported on any convenient structure suchas I beams 3 and 3 In casting 1 are provided stone pockets 1 withretaining bars 1. The inverted cone hopper 4: is attached to the rings 1and'l The blank knife block half rings 5 and 5 are supported fromcasting 1. The knife block ring 6 is also supported on rings 5 and 5 andcasting 1. The vertical bearing 7 is carrie'don c'astingl 'andinturncarries shaft' 8. The impeller 9 is attach-ed to shaft 8. With inimpeller- 9 are "the vanes 1-9, Directly abovebut notattached'toimpeller '9 is" the feed hopper 10. The shaft 8 is driventhru bevel gearsdl and 12,iwhich' in turn are driven= thruf shaft 13 andclutch pulley 1 1. The shaft 13 i's' 'supportedby bearings 15, 15 and15Gears 11 and 12ar'eenclosed in casing 16.

ring- 6 areof' the conventional design and are shown in larger detail inFigures 3, 4 and'5. Thelolank flknife blocks 18 are carried inthe-"rings 5and 5 These blank knife' blocksha ve; practically thesameidimensions as the knife :block' 17. When the knife bloc-ks 17' areremoved from. the ring 6 the-blankknife blocks 18 slide'into their placein'ring G-fromrings 5iand 5 'When the blocks 17' and 18 arein place in?the rings a 6='and '5 "and '5 their position is shown in Figure 5. Theh'eads'ofthebolts 17 hold the blocks 17 and 18 together as a unitwhilein"the'"rings 6,5 and 5. "When the blank block-18 is in the ringG intheplace offthe knifeblock 17,- it is j attached or detached from'theknife block 17 by sliding in or'out, the bolts '17? coincidinglvvithslots 18 -Theknife block 17"is conventional and is composed of theframe 17 b which carries the standard corrugated knives 17 and thecorrugated rocker bar 17 The knife blocks 17- are held in ring 6 by aremovable corrugated stop bar 19, which is secured to the ring 6 bydowel pins 19 and bolts 19".

The object of having bar 19 removable is to be able to substitute a barwith corrugations to coincide with those of the knives 17 The feedingdevice shown in Figures 8 and 9 is comprised of the stationary hopper 10With a baffle plate 10. Directly below hopper 10 is the rotatingimpeller 9. Within the hopper 10' is a multivaned feeder 10*, I

secured to and driven by shaft 10, which in turn is secured to anddriven by pulley 10 The belt 20 drives the pulley 10 at the requiredspeed from shaft 13 and pulley 13.

The operation of my beet slicer is as follows: The beets are depositedinto stationary hopper 10 and are fed by the feeder 10* into therotating impeller 9. Centrifugal force throws the beets against thestationary knife blocks 17. The beets are prevented from sliding orrotating in the impeller 9 by the vanes 9*. r

The stationary knives 17 in blocks 17 present sharp edges against whichthe beets are moved at a high peripheral speed, resulting in acontinuous stream of slices or cossettes being deposited from the knives17 into the hopper 4,

. Should any foreign matter, like stones, find its way into the cutterit will be lodged in the stone pocket 1 and can be removed by theraising of barsl.

I claim: r

L'In a beetcutter, the combination of stationary slicing elements, arotating element having a centrally located inlet passage diverging intoa plurality of spiral peripheral outlet passages which match with thestationary slicing elements, and blank elementsin position to besubstituted for the slicing elements.

2. In a beet cutter, the combination of a feeding device, a horizontalrotating element having an inlet opening concentric above its verticalaxis, the inlet opening being partitioned by vanes to form a pluralityof outlets, stationary cutting elements with which said outlet passagescoincide, blank elements in position and adapted to be substituted forsaid cutting elements, and means for driving the feeding device and thehorizontal rotating element.

3. In a beet cutter, the combination of a feeding device, a horizontalrotating element having an inlet opening concentric above its verticalaxis, the inlet opening being partitioned by vanes to form a pluralityof outlets, stationary cutting elements with which said outlet passagescoincide, blank elements in position and adapted to be substituted forsaid cutting elements, means for driving the feeding device and thehorizontal rotating element, means to receive hard or foreignsubstances, and removable means whereby said foreign substances areremoved from the machine.

4:. In a beet cutter, the combination of a rotary impeller having acentral inlet and a plurality of lateral outlets, removable knife blocksconcentric therewith, and means for receiving and removing hard orforeign substances from the machine.

5. In a beet cutter, the combination of a vaned type of feeding device,means for driving the same, a horizontal closed vaned type of impellerrotating therebelow, means for driving the impeller, the impeller havingperipheral openings, removable stationary knife blocks, blank blocksadapted to be substituted therefor, and slotted concentric rings forholding said blocks in a definite position.

6. In a beet cutter, the combination of a rotary impeller having acentral inlet and a plurality of lateral spiral outlets, verticallyslidable knife blocks concentric therewith, and blank blocks removablyattached at the lower edges thereof.

7 In a beet cutter, the combination of a rotary impeller having acentral inlet and a plurality of lateral outlets, vertically slidableknife blocks concentric therewith, blank blocks having slotted laterallyextended flanges at the upper edge, and bolts extending through theslots in the flanges into the lower edge of the knife blocks.
